BATH-TUB "HEATER.

amu e sr cereeled s m-2a, 9 4- Application filed septeniher tl l aliin. Seria1No.79,2,055. it a 1' b all LUILOI/L- it may concern 330 it known that 1, JOHN N. Tiaonn'rolv, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful improvements in Bath-Tub Heaters, of wh1ch the following is a specification.

The present invention relates to improve,

in accordance with the present invention inuse. Fig. ,2 is a detail plan view of the heater. Flg. 3 1s a cross sectlonal v1ew, substantially on the line 83 of Fig. 2, on an enlarged scale. Fig. i is an. enlarged detail longitudinal section of the inletend otthe device.

Referring to the drawings, 1 designates a bath tub which is provided with suitable water supply and waste pipes. i

As the heater hereinafter described adapted fer use with tubs 01"- various forms and sizes, the tub and its usual adjuncts are shown more or less conventionally.

The heater, as shown, comprises essentially a tube provided at one end with an inlet adapted to be connected by a flexible pipe 2 with a gas supply pipe 3 and bent upon itself to provide a series of substantially parallel connected members in each of which is founed plurality of upwardly directed burner outlets. As shown, the tube is bent to pro ide three parallel members 5, 6 and 7, connected as shown and so spaced that the flame issuing from the several outlets 4 will be directed against substantially the entire surface of the bottom of the tub 1 between the feet or supports therefor. As shown, the tube has oneend closed by. a cap 8 and its other end provided with a tapering nipple 9 over which one end of the flexible tube can be engaged and which is further proided with an inwardly directed extension 10 that constitutes the gas inlet of the heater.

at timeswhen the means water prior to its being introduced 1nto the In body of the tube, adjacent the inner end of the part .10, are formeclaplurality The heater is supported by legs 12, three being shown. Each leg 12 surrounds the tube forming the body of the heater and is adapted to be turned thereon so that the device may be properly supported and maintained 1n the des1red horizontal relation to the bottom of the tub 1, even if the floor on which it rests is uneven, as indicated in Fig. 3. Set screws 13 are provided for rigidly securing'each leg in the desired adjusted position. The adjustment of the legs relatively to the body of the heater above described also enables ,the distance between the device and the bottom of thejtub to be varied, asit will be evident that the tube will be supported at itsgreatest height and closer to the bottom; of the tub when the several legs are in vertical position than when said legs are inclined or turned from the vertical position.

The manner of using and advantages of such aheaterwill be readily understood and appreciated.

It will be seen that the invention provides a very simple, durable and inexpensive device which can be readily placed in position beneath a tub, or removed, it not desired.

By use of such a heater the temperature of water in the tub can be quicklyraised and the device is particularly ap Jlicable for use tub are inoperative.

Having thus described the invention what is claimed and desired to be secured by Letters Patent is:

1. The herein described bath tub heater comprising a tube having a suitable gas inlet and a series of upwardly directed burner outlets, legs embracing the tube and each independently adjustable about the tube to extend therefrom at any desired angle, and

means for securing the legs rigidly to the tube in any adjusted position.

2. The herein described bath tub heater comprising a tube having air and gas inlets adjacent one end and bent upon itself to provide a plurality of substantially parallel members eachprovided with a series of upor heating the wardly directed burner openings, a plurality of legs each. having a portion surrounding one of said members and adapted to turn thereon to extend at any desired angle from I burner openings, and legs connected with the tube, and means for securing each leg the tube and bodily adjustable relative therein any adjusted position. p l to for the purposes described.
